The Vilna Gaon said that the 20th and 42nd days of the Omer were special days, spiritual windows of opportunity with respect to the Redemption of the Jewish People.
As such, they are good days to pray extra hard for the arrival of Moshiach and the Final Redemption. These two days, more than the other 363 days of the year, are good opportunities to give thanks to God that we are still here as a people, and living on our land once again. Neither is a small miracle.
What redemption-yearning person would want to pass up such an opportunity? What Jew who prays for redemption at least three times everyday in his Shemonah Esrai would not want to take advantage of such a unique window to geulah shlaimah?
Yet each year, millions of religious Jews shut the window of spiritual opportunity on these two days of the Omer. For decades now, the 20th and 42nd day of the Omer have come and gone, and many redemption-oriented did little to use them to further the cause of redemption.
How can that be?
The answer is simple. The 20th day of the Omer happens to be Yom HaAtzmaut, Israel Independence Day, and the 42nd day is Yom Yerushalayim—Jerusalem Day.
[. . .]
The 20th day of the Omer has once again come and gone, and so many people who should have used the opportunity to push for the Final Redemption, did not. When the 42nd day rolls around in another two weeks, let’s not waste it. Let’s not be fooled, again, by the Sitra Achra. Let HIM be fooled by US when we push away distraction to get to the real spiritual opportunity of such a holy day.
